Django DBベストプラクティス

Question

私はDjangoでオンラインロールプレイングゲームを構築しています。私は考え、私は一種のdbのnoobのだ

class Equipment(models.Model): 
    head = models.ForeignKey("InvSlot",null=True,blank=True,related_name="head") 
    chest = models.ForeignKey("InvSlot",null=True,blank=True,related_name="chest")

    def __unicode__(self): 
     return self.item.name + " x " + str(self.quantity) 

class Character(models.Model): 
    fbid = models.CharField(unique=True, max_length=200) 
    name = models.CharField(unique=True, max_length=200)

    burned = models.BooleanField(default=0) 

    def __unicode__(self): 
     return self.name 

と：私はここでは、将来的には私の痛みを引き起こすないような方法でモデルを記述するための最良の方法は、私がこれまで持っているものが何であるか疑問に思ってこれを設定するより良い方法があるかどうかについてのいくつかの指針が本当に好きです。

Answer 1

Southのようなデータベース移行ツールを調べるとよいでしょう。これは、アプリケーションがデプロイされ、新しいバージョンでモデルの変更が必要になった後で、データベース更新の苦痛を抑えるのに役立ちます。
